Ultrafine Ni2P nanoparticles embedded in one-dimensional carbon skeleton derived from metal-organic frameworks template as a high-performance anode for lithium ion battery

摘要

The exploration of high-performance anode materials by designing different synthesis methods is crucial to the development of next generation lithium ion batteries (LIBs). Ultrafine Ni2P nanoparticles embedded in one-dimensional carbon skeleton derived from metal-organic frameworks template are obtained and used as LIBs anode electrode. The unique architecture of Ni2P@C electrode delivered a high capacity of 610.4 mA h g(-1) at the current density of 100 mA g(-1), excellent rate capability and superior cycling stability with no obvious capacity decay over 400 cycles at a high current of 500 mA g(-1), indicating the promising potential for LIBs application. Significantly, this design method of nanoparticles embedded in carbon skeleton may become a novel strategy for synthesizing other metal phosphides used as next generation LIBs anode materials.
